    These precision-machined inner rings can be used as raceways for rolling elements, or for seal lips when the shafts are unsuitable. Each features hardened steel construction, which helps to offer long service life. They are also suitable for use where needle roller bearings must be combined with wider inner rings in order to allow larger axial shaft displacement in relation to housing. The optimum running surfaces are required for seal lips.
